The American Liberty High-Relief Gold series began in 2015, with the release of the first gold bullion coin with a $100 face value denomination. Modern Liberty gold coins are struck at the West Point Mint on 1 oz. .999 fine gold planchets, with a High-Relief strike. High-Relief designs are raised from the coin surface, resembling mini-sculptures rather than traditional coins. Using a thicker coin with a smaller diameter, results a concave background with raised designs, and a realistic 3D appearance.
The first American Liberty coin was issued in 2015 with a new design, that changes every other year. The 2015 American Liberty High Relief Union features a Standing Liberty holding a torch and an American flag on the obverse, and a Flying eagle with olive branches in its talons on the reverse. The 2017 American Liberty 225th Anniversary Union obverse features a modern, youthful, African-American Liberty, wearing a crown of stars and dual-date 1792 – 2917, with the reverse portraying a American Bald Eagle in flight. The 2019 American Liberty 24k gold union features Liberty with 13 rays arising from her headdress on the obverse, and American Eagle preparing to land on the reverse.
